March 20, 20179 yr comment_759374 Is there any way to delay a transformer secondary ? I wanted to build the GG with a single transformer... Report
March 20, 20179 yr comment_759376 If you use GRHV supplies with “switch” – there are all kinds of supplies now days – it’s fairly easy to arrange a delay, even with a flashing led during pre-heat and steady in operation mode. Report
March 20, 20179 yr comment_759378 I used on my carbon an arduino and a solid-state rele. I'm doing the same thing on this PSU. Report

I assume these cases are from China? Any hint as to who/where they are from? Everytime I see one of your pics, I keep thinking I like those... Report

April 7, 20179 yr comment_761331 Has anyone used the 450 volt configuration? I´m waiting for a Mouser´s BO and I can´t do nothing Report
April 8, 20179 yr comment_761402 I'm building it with +-450V supplies. Still a bit afraid of the possible short between B- connection and the feedback trace, like it happened to insanity's Carbon. Edited April 8, 20179 yr by G600 precisions Report
April 8, 20179 yr comment_761407 Not built, still waiting for the custom transformer, and a bigger issue is the lack of a drill press and the related skills. Still being a very young padawan in DIY. Need some more weeks before completion. Edited April 8, 20179 yr by G600 Report
April 8, 20179 yr comment_761409 Anyone has spare boards laying around ? Very interesting in it, please PM me Report

Still being a very young padawan in DIY. Need some more weeks before completion. Yes, I´m waiting for two trafos too. TS300VA PRI: 230V > 2x360V @350mA > 18-0-18V @600mA And: TS50VA PRI: 230V SEC: > 6,3V @8A I don´t think that you have problems again if you use the "top" board (tube side) for put the conector.

April 10, 20179 yr comment_761524 For sure ! I use the RENY screws I have left from the T2, with spring washers over standard washers. Outstanding stuff from Chemis. The steel screw you can see just holds the board in place. Edited April 10, 20179 yr by G600 Report
April 10, 20179 yr comment_761535 Nice going, I can not wait to hear your impressions between GG and T2 Report
April 12, 20179 yr comment_761737 Received the transformer today. Didn't imagine such a big boy. But perfectly built. Changing plans for casing, unless it won't fit. Despite some mistakes and need of adjustment (make the tubes symmetrical for sure), you get the idea : Edited April 12, 20179 yr by G600 Report

April 13, 20179 yr comment_761796 Nice work G600 I can not see the tag of your trafo but I have one question: EL34 uses 6.3vol @ 1.5A, if you use four EL34= 6.3vol @ 6A. Your trafo only have 4.5A current so I understand that your transformer goes very low in amperage. Edit: Sorry, it´s 2x 6.3volt @ 4.5A Edited April 13, 20179 yr by jose Report
